Abstract: In some examples in accordance with the present description, an electronic device is provided. The electronic device includes an image sensor and a controller. The controller is to receive multiple images from the image sensor including respective foregrounds and backgrounds. The controller is also to segment the respective foregrounds from the backgrounds. The controller is also to combine the backgrounds to form a fused background. The controller is also to receive a new image including a new image foreground and a new image background. The controller is also to segment the new image foreground from the new image background.

Abstract: In examples, an electronic device is provided. The electronic device includes a processor to receive an input image from an image sensor. The processor is also to scale a size of the input image to a programmed size. The processor is also to encode the scaled input image to provide a feature map having a fractional size of the scaled input image. The processor is also to process the feature map according to lite reduced atrous spatial pyramid pooling (LR-ASPP) to provide a LR-ASPP result. The processor is also to decode the LR-ASPP result to provide an image segmentation result.

Abstract: In one example in accordance with the present disclosure, a system is described. The system includes a pose estimator to identify a plurality of anatomical points on a person depicted in an image. A frame former of the system generates a frame for the person by connecting a first set of the plurality of anatomical points to form a skeleton and forming at least a head region and a torso region of the person based on a second set of the plurality of anatomical points. A map generator of the system generates a spatial gradient map projecting outwards from the frame. In the system, the spatial gradient map is based on pixel distance from the frame and an intensity along the gradient map indicates a pixels likelihood of form a part of the person.

Abstract: In some examples in accordance with the present description, an electronic device is provided. The electronic device includes a controller to implement an image segmentation process. The controller is to obtain color information of an image. The controller also is to obtain depth information of the image. The controller also is to determine a depth of a face represented in the color information. The controller also is to segment a foreground of the image from a background of the image according to the color information and the depth information based on the depth of the face.

Abstract: Examples disclosed herein provide the ability for a computing device to adjust settings on a computing device. In one example method, the computing device captures, via a first sensor of a computing device, images of an environment that the computing device is currently in, and detects objects in the environment as captured by the images. As an example, the computing device determines a location of the environment based on contextual data gathered from the detected objects and adjusts a setting on the computing device based on the determined location.

Abstract: In some examples an electronic device includes an image sensor and a processor. The processor is to determine an angle of an eye gaze of a user in relation to an optical axis of the image sensor and adjust, responsive to a determination that the angle exceeds a threshold angle, an active area of a display device.
